Patent CA-2069099-A1 (CA)
Title: Card cage
Inventor: KOHT LOWELL I
IPC: G02B6/00
Filed: 1990-11-21
Abstract: Abstract of the Disclosure A card cage for housing a plurality of circuit boards and passive optical fiber couplers contains a tray for storing express optical fibers of express optical fiber tubes not to be coupled within the card cage but rather expressly routed through a distribution point accommodating the card cage. The tray has a flexible hinge thereon and means for keeping the tray passively deflected away from the optical couplers for facilitating insertion and removal of optical fibers into and from the couplers. A card cage housing snap fits to a card cage base without requiring screws or other physically detachable elements. The housing also includes a plurality of flexible deflectable clips integrally molded as part of the card cage housing which normally keep the circuit cards or boards within the card cage housing but which are deflectable so as to allow the boards to be slideably inserted and removed from channels within the housing for guiding the boards. The card cage further includes a backplane from which a plurality of test pins extend externally from the card cage so as to allow an electrical integrity of the card cage to be easily tested.
Patent CA-2072744-A1 (CA)
Inventor: WALTZ ALBERT J
IPC: F23N5/00
Filed: 1990-11-02
Abstract: A means of controlling a process with a multiplicity of measurements dependent on one process parameter, so that only the most constraining of the measurements manipulates the process in such a way that the performance of each individual controller selected is equivalent to the performance if there was a single controller controlling only one measurement, the most constraining variable. The means of controlling also manipulates the process to prevent a measurement, that is within a process constraint limit; from excessively exceeding that process constraint limit when it is projected that it would do so without the corrective manipulation.

Title: Slow-wave electrode structure
Inventor: JAEGER NICOLAS A F
IPC: H01P9/00
Filed: 1992-09-01
Abstract: A slow-wave electrode structure suitable for use in integrated optical modulators having a pair of spaced substantially parallel integrated optical waveguides in a compound semi-conductor substrate (such as gallium arsenide (GaAs) or indium phosphide (InP)) is formed by a pair of substantially parallel conductor strips on the surface of the substrate each in a position for interaction with its respective adjacent of said waveguides. The conductor strips are capacitively interconnected by narrow fins each integral with one of the strips and extending between the strips whereby the conducting strips and fins may be applied as a single layer to the substrate. The narrow fins significantly increase the capacitance per unit length between the strips without an equivalent decrease in inductance per unit length along the strips such that the phase velocity of the microwave signals is reduced.
